don't know anything specific to TPTP but if this method is called
often then cumulative code will be high.
I couldn't find anything related to TPTP either. It has huge "Average
Base Time (seconds)" value for such method which is 0.046532 and it is
called only 1713 times.
I guess the question is why the average is so high for it.
Maybe this method is triggering jit compilation and skews the results ?
But what I can see now XModel thing just first reason of performance
issues IMO. We must do something and clean it up. It just loads
processor without any reasons. I see calls counters is growing up even I
just sit and do nothing.

Just guessing...
